Essentially, for observers within different inertial frames of reference different relative velocities , both the shape of space as well as the measurement of time simultaneously change due to the invariance of the speed of light — a view vastly different from Newton's. Practical examples Example 1: You might wish to cook a meal which needs to be in the oven for 6. However, in 1967 it was redefined as the duration of 9,192,631,770 energy transitions of the cesium atom.
